Systems and methods provide adaptability in a mobile ad hoc network (MANET), based on an existing protocol, such as adaptive hybrid domain routing (AHDR). The systems and methods are especially suited for fast changing topologies that may change after a reactive route discovery has been completed.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for adaptively selecting a domain lead node from among a set of nodes in a mobile ad hoc network, the method comprising: (a) establishing a link change threshold percentage; (b) establishing a threshold delta link state level (LSL) increment value; (c) calculating, by each node in the network, for each node in the network what percentage of links have changed by more than the threshold delta link state level (LSL) increment value; (d) determining, by each node in the network, if the calculated percentage of changed links for the given node exceeds the link change percentage threshold; (e) adaptively computing, by each node in the network, a node coverage value (NC) for each node from among the set of nodes in the network by adaptively adjusting a state value, s 0 , for each node, downward, in response to satisfying said determining step (d); and (f) selecting, by the set of nodes in the network, said domain lead node from among said set of nodes in said network based on a highest computed node coverage value (NC).
2. A method according to claim 1 , wherein said determining step (d) is performed at successive update increments.
3. A method according to claim 1 , wherein the link change threshold percentage is adjusted in accordance with a type of network.
